PASTE-FOUNTAIN FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 686,337, dated November 12, 1901.

Application filed January 21,1901. Serial No. 431970. tNo model.)

` county of Kings, and State of New York, have invented certain new and useful Improvements in Paste-Fountains for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in devices for applying to moving material, such as a web or sheet of paper, liquid--such, for instance, as paste-in a line or lines. t

The pasting devices noW ordinarily used in the art, and more particularly those which are used in connection with fast rotary printing-machines, employ a wheel or blade, to which paste is applied and with which the passing Web or sheet is brought into contact, the wheel being used when the line of paste is to be lengthwise of the web or parallel with its run and the blade being used when the line of paste is to be applied transversely of the material orto its run. The movement of these pasting blades or Wheels is necessarily rapid, and there is always liability that the paste will be thrown or iiirted off the pasting device onto the material, this being especially the case Where transverse pasting-blades are employed. Furthermore, the transverse pasters specially are complicated and expensive in construction.

The object of this inventionis to produce a simple, compact, cheap, and efficient device which may be used for applying paste or other similar substances to material, such as a web or sheet, and which avoids the objection heretofore stated.

With this and other objects in view the invention consists incertain constructions and in certain parts, improvements, and combinations, as will be hereinafter described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, in which like characters of reference indicate the same parts, Figure 1 is a sectional side elevation of a liquid-applying device constructed in aecordance with the invention. Fig. 2 is a similar view illustrating a modification.

Referring to Fig. 1, which illustrates a conmanner and may be used for holding any desired liquid. In the present instance it is intended to hold paste and to be mounted in a printing-machine. The paste-applying device includes a suitable moving surface, upon which the paste is deposited, preferably in a line or lines. While this moving surface may be of any suitable character, it preferably consists of a cylinder 52, which may be constructed in any suitable manner so as to receive a line or lines of paste. In the preferred form of the construction, however, the cylinder will be provided with a plurality of grooves 53. While any suitable arrangement of devices may be used by which the paste from the fountain is transferred to the cylinder, in the preferred form of the construction the cylinder is mounted so as to rotate in the fountain and the fountain is provided with suitable means which operate to clean the surface of the cylinder, and therefore to prevent any liquid being carried out of the fountain by the cylinder except that which is deposited in the grooves 53. In the construction shown the cleaning devices consist of Scrapers 56 and 57, said Scrapers being secured in position by means of screws 5S or in any other suitable manner and being adjusted in an ordinary and obvious Vmanner by means of thumb-screws 59. Suitable means is employed to force the web or sheet of material into the grooves of the cylinder, and thus cause the paste to be deposited thereon. While this means may be varied in construction, it will preferably consist of a rotating blade 60, mounted on a shaft 61, which may be rotated in any desired manner. Both the cylinder and the blade are caused to move at the time when the paste is to be applied to the material, so as to avoid smudging or -streaking of the paste. The movement of the cylinder may be either constant or intermittent. In Fig. 1 a mechanism is shown for giving the cylinder an intermittent movement. anism may be employed for this purpose, in the preferred form of the construction an ordinary pawl-carrying arm 62 is mounted n IOO While any suitable mechr the journal of the cylinder, said arm carrying a pawl 63, which is held to its duty by means of a spring 6l. An operating-rod 65 is connected to said paWl-carrying arm, said rod being formed to provide a fork 66,which takes over the shaft 6l, on which the rod is mounted. The shaft 61 carries a closed or island cam 67, engaged by abowl 68, which is connected to the operating-rod 65. The cam 67 is so arranged as to operate the mechanism before described and cause the pawl to advance the cylinder a distance equal to the distance between the grooves 53 for each rotation of the blade GO, the movement of the cylinder occurring at the time when the blade 60 comes into engagement with one of the grooves 53.

The construction shown in Fig. 2 is substantially the same as that before described, with the exception that the cylinder 52 is continuously rotated and is provided with a single groove 53 instead of a plurality of such grooves. Any suitable mechanism may be employed for constantly rotating the cylinder. The cylinder preferably carries a gear 69, which meshes with a gear 70, mounted on the shaft which carries the blade 60.

By the constructions which have been described herein it will be seen that a transverse paster is produced in which the blade does not carry the paste, the paste being contained in a groove or grooves of the cylinder. There is no tendency, therefore, to throw or flirt the paste from the pasting device onto the web of passing material, and, furthermore, the construction, while very eflicient, is cheap and compact.

While the device is primarily intended for applying paste, it is equally applicable to the application of other liquids of a generally similar nature. While, furthermore, the invention is embodied in a pasting apparatus intended for the application of a line of paste transverse to the run of the material, it is not to be limited to such an apparatus. It will be further understood that while the apparatus which has been described is eective' for the purpose the details of construction by which the invention is carried into effect may be varied within wide limits.
